Solve for j if aj+k=v

**Answer:**

j=v-k/a

**Step-by-step explanation:**

It's like order of operations backwards. So first, you would get rid of the k, by subtracting it from both sides. Then, to isolate j you would divide both sides by a.

What is the answer tho

**Answer:**

to?

**Step-by-step explanation:**

uh what’s ur question?

find the value of x

The answer is 150.

I need to show my work.

THANKSSSS

**Answer:**

x = 150

**Step-by-step explanation:**

We know a circle is **360°**, so the angles must add up to 60°.

Step 1: Set up equation

x - 120 + x - 120 = 60

Step 2: Solve for *x*

Step 3: Check

*Plug in x to verify it is correct.*

150 - 120 = 30°

150 - 120 = 30°

30° + 30° = 60°

60° + 300° = 360°

Write the equation to find the value of x. (DO NOT find x, just write the equation.)

(2x - 10) (65 - x)

Part B

What is the value of x?

Y

**Answer:**

**Step-by-step explanation:**

just add up both alternate internal angles as they are both equal

so, the equation is: 2x-10 = 65-x

**Answer:**

The right equation will be 2x - 10 = 65 - x (you were wrong lol)

**Step-by-step explanation:**

We have: 2x - 10 = 65 - x

=> 2x - 10 + x = 65

=> 3x = 65 + 10 = 75

=> x = 75/3 = 25

A TV show has 26 episodes. Due to the lack of time, you can onlywatch 5 of them. However, in order to get a gist of what the showis about, you do not want to watch any two consecutive episodes.How many selections of 5 episodes are there with no two consecutiveepisodes chosen? Assuming that the order of selection is irrelevant.(Hint:this is a Stars and Bars problem)

**Answer:**

**Step-by-step explanation:**

Recall that: The number of combination to select any k consecutive element from n consecutive term is given by the equation [tex]^{n-k+1}C_k[/tex]

[tex]= \begin {pmatrix} ^{n-k+1}_{k} \end {pmatrix}[/tex]

where:

n = 26

k = 5

[tex]^{n-k+1}C_k= \begin {pmatrix} ^{26-5+1}_{5} \end {pmatrix}[/tex]

[tex]^{n-k+1}C_k= \begin {pmatrix} ^{22}_{5} \end {pmatrix}[/tex]

[tex]^{n-k+1}C_k= \dfrac{22!}{5!(22-5)!}[/tex]

[tex]^{n-k+1}C_k= \dfrac{22!}{5!(17)!}[/tex]

[tex]\mathbf{^{n-k+1}C_k=26334}[/tex]

Therefore, there are 26334 selection of 5 episodes with no two consecutive episodes chosen

what is 4/6+2/3.?(these are fractions, you're just adding fractions)

**Answer:**

4/3

**Step-by-step explanation:**

Multiply 2 by 2, and get 4, then we multiply 3 by 2 and get 6.

Since our denominators match, we can add the numerators. 4 + 4 = 8. That gives us the sum, which is 8/6. Then you divide by 2. So 8/6 / 2 gives you 4/3.

**Answer:**

4/3 or 1 1/3

**Step-by-step explanation:**

1. 4/6 + 2/3

2. 4/6 + 4/6 **You have to find the LCM (least common multiple) of the two denominators. In this case it would be 6. You have to multiply 3 by 2 to get 6. What you do to the bottom you also do to the top so you have to also multiply the numerator (2) by 2.**

3. 4/3 or 1 1/3 ** Afterward, you just have to add straight across without changing the denominator and then if you need to simplify you simplify. Without simplifying, you would get 8/6, but, most teachers will mark it as wrong if you don't simplify. You can then change the improper fraction into a mixed number depending on what your teacher wants.**

Use the information to find the minimum sample size required to estimate an unknown population mean µ. Margin of error: $110, confidence level: 95%, σ = $500. Group of answer choices

**Answer:**

The minimum sample size required is **79**.

**Step-by-step explanation:**

The following are given in the question:

e = Margin of error = 110

σ = Standard deviation = 500

Confidence level = 95%

n = Minimum sample size = ?

Therefore, we have:

Zσ = 1.96 at 95% confidence level

s.e. = Standard error = σ / [tex]\sqrt{n}[/tex] = 500 /

Alternatively, margin of error can be calculated as follows:

e = s.e. * Zσ = 110 ................... (1)

Substituting the other values into equation (1) and solve for n, we have:

500 / [tex]\sqrt{n}[/tex] * 1.96 = 110

500 / [tex]\sqrt{n}[/tex] = 110 / 1.96

500 / [tex]\sqrt{n}[/tex] = 56.1224489795918

500 = 56.1224489795918 * [tex]\sqrt{n}[/tex]

[tex]\sqrt{n}[/tex] = 500 / 56.1224489795918

[tex]\sqrt{n}[/tex] = 8.90909090909092

[tex]n^{\frac{1}{2}[/tex] = 8.90909090909092

Squaring both sides, we have:

([tex]n^{\frac{1}{2}[/tex])^2 = (8.90909090909092)^2

n = 79.3719008264465

Approximating to a whole number, we have:

n = 79

Therefore, the minimum sample size required is **79**.

Think of a problem that you may be interested in that deals with a comparison of two population means. Propose either a confidence interval or a hypothesis test question that compares these two means. Gather appropriate data and post your problem (without a solution) in the discussion topic. Later, respond to your own post with the solution for others to check their work. For example, you may want to know if the average weight of a rippled potato chip is the same as the average weight of a non-rippled potato chip. You may weigh rippled regular potato chips fro m a large bag and find weights of 1.7,1.9,2.4,1.3, 1.7, and 2.0 grams. You may weigh non-rippled potato chips from another larg bag and find weights of 1.8, 1.6,1.9, 1.9, and 1.4 grams. Assume a random sample was drawn. Think of a problem that you may be interested in that deals with a comparison of two population proportions. Propose either a confidence interval or a hypothesis test question that compares these two proportions. Gather appropriate data and post your problem (without a solution) in the discussion topic. Later, respond to your own post with your own solution. For example, you may believe that the proportion of adults in California who are vegetarians is more than the proportion of adults in New Hampshire who are vegetarians. In two independent polls, you may find that 109 out of 380 California residents are vegetarians and 39 out of 205 New Hampshire residents are vegetarians. For your response to a classmate (two responses required, one in each option), solve your classmate's confidence interval or hypothesis test problem, using a significance level not previously used Make sure that you use appropriate terminology and specify whether you are using the classical method or the p-value method.

Answer:

**Responds to my friend**

**Decision rule **

Fail to reject the null hypothesis

**Conclusion **

There is no sufficient evidence to conclude that the proportion of residents in California who are vegetarians is higher than the proportion in New Hampshire who are vegetarian

Step-by-step explanation:

Here we are going to consider this question

** For example, you may believe that the proportion of adults in California who are vegetarians is more than the proportion of adults in New Hampshire who are vegetarians. In two independent polls, you may find that 109 out of 380 California residents are vegetarians and 39 out of 205 New Hampshire residents are vegetarians.**

** **Here we are going to be solving the hypothesis test problem and we will be making use of the p-value method

From the question the we are told that

The first sample size is [tex]n_1 = 380[/tex]

The second sample size is [tex]n_2 = 205[/tex]

The number of California residents that are vegetarian is [tex]k = 109[/tex]

The number of New Hampshire resident that are veterinarian is [tex]u = 39[/tex]

Generally the sample proportion for California residents is

[tex]\^ p_1 = \frac{k}{n_1}[/tex]

=> [tex]\^ p_1 =\frac{109}{380}[/tex]

=> [tex]\^ p_1 = 0.2868 [/tex]

Generally the sample proportion for New Hampshire residents is

[tex]\^ p_2 = \frac{39}{205}[/tex]

=> [tex]\^ p_2 = 0.1902 [/tex]

The null hypothesis is [tex]H_o : p_1 -p_2 = 0[/tex]

The alternative hypothesis is [tex]H_a : p_1 -p_2 > 0[/tex]

Generally the test statistics is mathematically represented as

[tex]t = \frac{(\^ p_1 - \^ p_2 ) -0}{\sqrt{ \frac{\^ p_1 (1-\^p_1 )}{n_1} + \frac{\^ p_2 (1- \^p_2)}{n_2} } }[/tex]

=> [tex]t = \frac{( 0.2868 - 0.1902) -0}{\sqrt{ \frac{0.2868 (1-0.2868 )}{380} + \frac{0.1902(1- 0.1902)}{205} } }[/tex]

=> [tex]t = 0.036[/tex]

Generally the degree of freedom is mathematically represented as

[tex]df = n_1 + n_2 -2[/tex]

=> [tex]df = 380 + 205 -2[/tex]

=> [tex]df = 583/tex]

Generally the probability of [tex]t = 0.036[/tex] at a degree of freedom of [tex]df = 583/tex] from the t- distribution table is

[tex]p-value = P(t > 0.036) = 0.48564732[/tex]

Let take the level of significance to be [tex]\alpha = 0.05[/tex]

So from the values obtained we see that [tex]p-value > \alpha[/tex] hence the decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to conclude that the proportion of residents in California who are vegetarians is higher than the proportion in New Hampshire who are vegetarian

a stone which is dropped into a dry well hits the bottom in 2.2s how deep is the well. take g=10m/s

**Answer:**

**23.7m**

**Step-by-step explanation:**

Given parameters:

Time taken = 2.2s

Acceleration due to gravity = 10m/s

**Unknown: **

Depth of the well = ?

**Solution: **

To solve this problem, we simply apply one of the motion equations;

S = ut + [tex]\frac{1}{2}[/tex] gt²

where S = depth of the well

u = initial velocity

t = time taken

g = acceleration due to gravity

Input the parameters and solve for S;

Note initial velocity = 0;

S = [tex]\frac{1}{2}[/tex] x 9.8 x 2.2²

** S = 23.7m**
